FWIW:
I never been to AK. But many of the local fishing guides here in Ory-Gun split time in the AK rivers.
The general consensus is that a 375 (H&H or Ruger) is a bear defense weapon.
That being said, most of the Fishing guides carry that thing between their ears for bear protection.
If you placed me in a Defense of Life situation tomorrow, I would use my Remington 870. Because that is what I have trained with and have become most proficient with. It also has pretty good power and can be loaded with 400 grain nosler partition sabot loads:
Good luck.
Oh--If your wife is asking, you need a new gun!!!!
